Fluvial suspended sediment transport is described by various quantitative and qualitative parameters. Thanks to the recent technological advances, using of state-of-the-art indirect measurement techniques (as reliable alternatives) in suspended sediment measurements has also come to the fore. However, indirect methods are typically sensitive to changes in suspended sediment quality (e.g. particle size and material).
In this research, investigations are carried out at the confluence of two rivers with different sediment characteristics. Following the direct and indirect suspended sediment sampling at the field, the sediment samples are analysed in the laboratory using a variety of analytical methods. The data processing is supplemented by a comparative analysis of the obtained results and the drawing of conclusions.
